DRIVING-GEAR.

SPECIFICATION forming part of Letters Patent No. 624,816, dated May 9, 1899. Application filed May 6 1898. Serial No- 6'79,952. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS E. JARv1s,-of Stockbridge, in the county of Madison and State of New York, have invented a new and,

Improved Driving-Gear, of which the following is a full, clear, and exact description.

This invention relates more particularly to driving-gear operated by a wind-wheel; and the object is to provide a gear so constructed that the band-wheel at the lower portion of the shaft may be turned on a horizontal plane to any desired position and secured so that it may be placed-in band connection with any one of a number of machines that may be placed variously around a barn-floor or the like.

I will describe a driving-gear embodying my invention, and then point out the novel features in the appended claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is an elevation, partly in section, of

a driving-gear embodying my invention. Fig' 2 is a section on the line 2 2 of Fig. 1, and Fig. 3 is a section on the line 3 3 of Fig. 1.

Referringto the drawings, 1 designates a power-shaft operated from a windmill or the like. This power-shaft has a bearing through a sleeve 1, extended through a hub 2, 0n the lower end of which is a plate 3. This hub and plate are seen red to the lower end of a mast 4.

As here shown the mast is arranged between cheek-plates 5, extended from the hub and plate. .Mounted to rotate on the shaft 1 below the plate 3 is a plate 6, secured to the upper end of a block 7. The plate 6 is provided with an annular row of holes 8, and the plate 3 is also provided with holes 9. A pin 10 is designed to be inserted through one of the holes 9 and through one of the holes 8, thus holding the plate 6 as rotatively adj usted with relation to the plate 3. The sleeve 1 is extended from the plate 6, and attached to the upper end of the'sleeve is a ring 1', which engages on the upper end of the hub 2 and serves to support the plate 6, the block 7, and other parts carried by the block.

Secured to the shaft 1 below the plate 6 is a clutch-section 11, designed to be engaged with the upper portion of a clutch-section 12, movable longitudinally of the shaft 1. The lower end of this movable clutch-section is adapted to be engaged with a clutch-section 13, secured to a shaft 14, having a bearing through a casting 15, attached to the lower end of the block 7. The shaft 1 extends some* what into the clutch-section 13, but of course is separate from the shaft 14.

To the lower end of the shaft 14 is affixed a bevel-gear 16, meshing with a bevel-gear 17 on a counter-shaft 18, having bearings in the casting l5 and provided at its outer end with a band-wheel 19. The clutch-section 12 is at all times in connection with the clutch-section 11,and it may be moved into and out of engagement with the clutch-section 13 by means of a lever 20, fulcrumed on the block7 and having its end engaged in an annular in engagement the shaft 14 and its gearing will be rotated by means of the shaft 1, and of course when the section 12 is moved out of engagement with the section 13 the shaft 1 may rotate without imparting motion to the shaft 14.

When it is desired to move the band-wheel to anew position, after removing the pin 10 the block 7, to which the casting 15and the ring 6 are attached, is to be swung around. This of course swings the band-wheel19. The dotted lines in Fig. 1 indicate the band-wheel as swung to the reverse position, in which it is shown in full lines. One band, which may always be an open belt, will run the machine in either direction, and by this invention I have the benefit of line-shaftingand still not draw on the power any more than if it were not there. No extra boxes or bearings are required.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A driving-gear comprisinga driving-shaft, a fixed plate through which the shaft extends, a rotatively-adjustable plate bearing against the under side of the fixed plate and supported by said fixed plate, means for securing the adjustable plate as adjusted relatively to the counter-shat t and the short shafmsubstantially as specified.
